Example of pathologies of the superficial sensory branch of the ulnar nerve. A Short-axis view of the superficial sensory ulnar nerve just distal to the pisiform bone showing a hypoechoic enlargement of the nerve representing neuroma-in-continuity in a patient subjected to trauma to the wrist and palm. Note the normal size and appearance of the deep motor ulnar nerve. B Long-axis view of the lateral branch of the superficial sensory ulnar nerve at the proximal palm in another patient subjected to a palm trauma showing abrupt end of the nerve denoting nerve transection with formation of proximal stump neuroma
